Problems solved by technology

These methods provide a reference for the study of the oral deposition behavior of cigarette mainstream smoke, but there are still deficiencies in cavity structure design, airflow control, temperature control, etc. There are still large differences in the situation, and the simulation effect of the smoke oral deposition behavior needs to be further improved

Embodiment 1

[0031] A 4cm×8cm filter paper coated with 0.5ml of artificial saliva was placed circularly along the inner wall of the simulated cavity, the constant temperature reflux water was adjusted to 37°C, and all parts of the device were connected, and then the cigarette sample was inserted into the cigarette end of the triangular valve. The suction volume of the single-channel smoking machine is 35mL, the suction time is 2s, and the suction cycle is 10s. Under this suction cycle, the residence time of smoke in the cavity is 8s. After the cigarette is smoked, switch the triangular valve to the air end while the smoke stays. When the smoking machine smokes again according to the above suction parameters, the smoke in the cavity is drawn out, and the smoke deposits are collected by the trap After the particle phase. So repeated, each cigarette smoked 10 puffs. According to the above-mentioned smoking method, 5 cigarettes were smoked, and the sediments of the smoke in the simulated cha...

Embodiment 2

[0036]A 4cm×8cm filter paper coated with 0.5ml of artificial saliva was placed circularly along the inner wall of the simulated cavity, the constant temperature reflux water was adjusted to 37°C, and all parts of the device were connected, and then the cigarette sample was inserted into the cigarette end of the triangular valve. The suction capacity of the single-channel smoking machine is 50mL, the suction time is 2s, and the suction cycle is 10s. Under this suction cycle, the residence time of smoke in the cavity is 10s. After the cigarette is smoked, switch the triangular valve to the air end while the smoke stays. When the smoking machine smokes again according to the above suction parameters, the smoke in the cavity is drawn out, and the smoke deposits are collected by the trap After the particle phase. Repeatedly, each cigarette takes 10 puffs. According to the above-mentioned smoking method, 5 cigarettes were smoked, and the sediments of the smoke in the simulated cha...

Abstract

The invention discloses a cigarette smoke oral cavity deposition simulation device and method. The device comprises a smoke suction part, a smoke deposition simulation cavity, a smoke capturing part and a suction part which are connected in sequence. The simulation cavity is an interlayer type cylindrical cavity, filter paper coated with artificial saliva is arranged along the inner wall of the cavity, and an interlayer is connected with constant-temperature circulating water; the smoke suction part comprises a three-way valve and a suction pipe, the suction pipe extends into the simulation cavity, the end of the suction pipe is closed, and air holes are evenly distributed in the end of the suction pipe. The device has the characteristics that: 1) the three-way valve is used for controlling the switching between smoking and empty smoking of the cigarette, so that the simulation of smoking, staying and swallowing of smoke in the oral cavity can be realized; 2) the suction pipe port air hole can ensure full diffusion of smoke in the cavity; 3) the cavity volume basically conforms to the oral cavity volume, the filter paper is used for simulating the oral mucosa and adsorbing the smoke in the cavity, the constant-temperature circulating water in the interlayer can simulate the oral cavity temperature; 4) and the trap can realize trapping of swallowing smoke particulate matters after the smoke stays in the oral cavity and is deposited.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a device and method for simulating oral cavity deposition of cigarette smoke. Background technique [0002] During the smoking process of cigarettes, the sweet, sour, bitter and other taste sensations and chemical sensations such as stimulation, burning, and coolness that consumers feel through the mouth are mainly due to the deposition of mainstream smoke in the mouth. Accurately grasping the deposition behavior of mainstream smoke in the oral cavity is of great significance for further in-depth study of cigarette consumers' oral physiological perception of smoke and its physiological mechanism. However, there is currently a lack of analysis methods for the oral deposition of smoke, and it is difficult to carry out relevant research in depth. CN102128913A discloses an oral cavity simulator and method for evaluating irritating components of cigarette smoke; CN105021741A disclose...
